三七果实发育中生理生化的动态研究

目的对三七果实发育过程中的生理生化变化进行研究。方法对三七果实发育过程中的生长情况、干鲜质量变化、含水量变化及可溶性糖、淀粉和蛋白质的量进行动态测定。结果在三七果实的发育过程中含水量先升后降,于成熟时达到73.37%;果实的鲜、干质量随果实发育逐渐增加,发育前期质量增加明显;淀粉和蛋白质的量同样随果实发育而逐渐增加,但发育后期质量增加较快;而可溶性糖的量则先升后降,到后期又略有上升。结论三七果实于盛花期后80 d达到成熟;在发育过程中,含水量的下降伴随着果实鲜、干质量的不断增加,而果实内营养物质的贮存及利用与果实的发育程度密切相关。

Dynamic studies on physiological and biochemical changes during fruit development of Panax notoginseng

Objective The physiological and biochemical changes were studied during the Panax notoginseng's fruit development. Methods Dynamic changes of fruits size, fresh and dry weight, moisture content and soluble sugar, starch and protein contents were investigated. Results The moisture content was increased first and then dropped to 73. 37%at maturity. The fresh and dry weight, starch and protein contents of P. notoginseng's fruits were increased with the fruit development. The soluble sugar content was raised first, then decreased, and increased slightly at the lateral stage of fruit development. Conclulion The P. notoginseng's fruits are mature at 80 d after peak anthesis;the decrease of moisture content is companied with the gradual increasing of fruit fresh and dry weight during the fruit development. The storage and utilization of nutrients in P.notoginseng's fruits are closely related with the fruit development.
